I heard the oil filter is easy to remove on these cars.

Thanks everyone! And yes, I don't baby any of my cars during break in. I'm a firm believer of "hard" break ins or "drive it like you stole it." I've done plenty of wot pulls.

Any opinions on oil for this vehicle? I don't have my owners manual yet (dealer forgot to include them), so I can only go by what people are saying on focus st forums, but most of them just argue back and forth. I'm at 900 miles on my factory fill. I was going to change my oil tomorrow, but I...

I didn't do anything to this oil.

Same Pennzoil ultra 5w-30 that I've always gotten. I've since switched to Mobil 1 0w-40

Got my 2nd report with PU 5w-30 http://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=3047279&#Post3047279

Oil sample for second uoa on PU has just been mailed out.

If this mobil 1 holds up great and protects my engine, it will be the best oil I have ever used. My engine is much quieter, the car runs noticeably smoother, it accelerates better, and I get better MPG. Seriously, this stuff is magical from all I experienced. I'm not imagining it either. My...

How long does it usually take for the oil to reach operating temp? Shortly after the coolant reaches operating temp?

Yeah, this is really weird. Here's my average mpg right now (I reset my trip counter when I changed to M1). this is with around 70% city driving. Now, I could RARELY even hit 25mpg with 100% highway driving when I had PU 5W-30. Very weird, but I'm not complaining. http://imgur.com/LqlcQJr.jpg

For some reason my mpg seems a little better on the 0w-40. I haven't changed my driving habits. Just checked the oil level after 100 miles. Still full.

I haven't heard of oil consumption with the 0w-40 M1, so maybe you are correct about shearing causing it.

So that means a thicker oil is even better for the 2008+ then right? Also, what exactly causes oil consumption? For some reason a lot of Subaru owners claim their cars "eat" Mobil 1, but not any other oil? Why would this be?

What causes oil consumption ?

I said screw it to the warranty. Flashed a stage 1 tune (stock tune knocks and runs lean well into boost), canceled my extended warranty, and just recently put 40wt oil in. The best warranty is one never used. Your statement about not recommending a subaru is a little unsettling though.

FYI, I don't support lying to your dealer about going against warranty requirements or anything, but the walmart receipt just says "mobil oil" for the 0w-40.
